Recommendations

  • Continue with biennial stream habitat assessments, in conjunction with annual macroinvertebrate monitoring, at all RWQMN sites.
  • Standardise the habitat assessment protocol so that reproducibility is easily achieved from one surveyor to another.
  • Carry out multivariate statistical analysis of the macroinvertebrate data with the habitat assessment and water quality data.
  • Investigate declining water quality/macroinvertebrate scores/stream health and stability at all sites that show a downward trend.
  • Implement a fish monitoring programme at all RWQMN sites, to complement the macroinvertebrate and habitat assessment data.
